Homework Statement
The Cosmoclock 21 Ferris wheel in Yokohama City, Japan, has a diameter of 100m. Its name comes from its 60 arms, each of which can function as a second hand (so that it makes one revolution every 60.0 s.
Part A:Find the speed of the passengers when the Ferris wheel is rotating at this rate.
-I used V=(2piR)/T and got 5.24 which was correct.
Part B:A passenger weighs 862 N at the weight-guessing booth on the ground. What is his apparent weight at the lowest point on the Ferris wheel?
-This is where I am completely thrown off course. Is it asking for the normal force? I thought apparent weight was just m*g?
Part C:What is his apparent weight at the highest point on the Ferris wheel?
-Same issue with Part B
Part D:What would be the time for one revolution if the passenger's apparent weight at the highest point were zero?
-I would need the proper formula from Part B to find Part D, so I'm stuck here too.
Part E:What then would be the passenger's apparent weight at the lowest point?
-Same issue as Part D
Homework Equations
V=(2piR)/T
Sum of the forces in the y direction= N=m(g-(v^2/R))
The Attempt at a Solution
I attempted to use that formula but it said it was wrong so I have no clue what to do now.
